IMPROVEMENT IN THlLL-COUPLINGS.

Specification forming part of Letters Patent No. 215,907, dated May 27,1879 application filed February 1, 1879.

To all whom it may concern:

Be it known that I, HIRAM F. GAINEs, of Keeseville, in the county ofEssex and State of New York, have invented a new and valuableImprovement in Thill-Couplings; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure l of the drawings is a representation of a side elevation of mythill-coupling; and Figs. 2, 3, and 4 are perspective detail views ofthe same.

The nature of my invention consists in the construction and arrangementof a thill-co'upling which is cheap, simple, and durable, and not liableto become accidentally detached, as will be hereinafter more fully setforth.

In the annexed drawings, A represents an ordinary axle-clip, with boltsa, cross-bar B, and nuts I). 7 From the front of the clip A extendforward two arms or ears, 0 G, which are made solid, without any holesthrough them. Near the front end, on the inner side of each ear 0, is avertical groove, (1, extendin from the top edge downward to or below thecenter of the ear.

D represents the thill-iron, provided at its end with an eye, F, for thepassage of the pin or bolt I, and this eye is at each end provided witha curved flange, p, to fit over the rounded forward ends of the ears 0,as shown.

The pin or bolt I is provided with a square head, h, and the other endis flattened on one side, as shown at i,- but if desired the head h maybe either round or half-round.

Between the ears 0 O is inserted a rubber block, G, the front side ofwhich is made eoncave to correspond somewhat with the convex surface ofthe eye F. The pin or bolt I is iusorted in the eye F, and said eyethenpressed from the top against the rubber block, so that the head and endof the pin will enter the grooves d in the ears (J, when the whole ispressed down till the pin rests in the bottom of said grooves.

This invention will enable one to shift shafts for pole, and vice versa,without delay or the necessity of using hammer or wrench. It avoidsaccidents, being so much easier to examine the condition of the bolt orpin, and there are no nuts to lose otf. It is simple, strong, anddurable, and can be manufactured cheaply of either wrought or malleableiron,

and is susceptible of as much or little ornamental finish as desired.

I claim The combination oi the clip A with solid ears 0 0, havinggrooves d d, the thill-iron D, with eye F, having side flanges p p, thepin or bolt I, and the rubber block G, substantially as and for purposesherein set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

HIRAM F. GAINES.

IMPROVEMENT IN MACHINES FOR SANDING AND SMOOTHING VENEERS.

Specification forming part of Letters PatentNo. 215,908. dated May 27,1879; application filed April 5, 1879.

:which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters of reference marked thereon, which form a part of thisspecification, and in which- Figure 1 is a side elevation of my improvedveneer or. board sanding or smoothing machine with one of thepulleysbroken away to better expose the parts. Fig. 2 is a verticallongitudinal section thereof, and Fig. 3 is a front elevation of thesame. Fig. 4 is perspective view of the bed plates or bars. Fi 5 is aninverted perspective view of the press ure-bar.

The same part in the several figures is denoted by the same letter.

This invention has reference ,to certain improvements in machines fortreating veneers or boards, the object of which ,is to avoid thesplitting or breaking of the veneers or boards a cause of great waste inmachines as heretofore constructed; and it consists, primarily, in thearrangement at the front end of the machine, opposite the feed-rollsthereat, of a bar or roll with its upper surface occupying a plane abovethe point of entrance between said rolls; and, secondarily, in theemployment, first, of a bed plate or bar arranged upon the front side ofthe smoothingor operating roll or cylinder with that edge next to thefeed-rolls beveled or chamfered; secondly, in the arrangement upon theopposite or rear side of the said cylinder or roll of a similar plate orbar with that edge next to the cylinder also beveled or chamfered; and,thirdly, in the general construction and arrangement of the parts,substantially ashereinafter more fully set'forth. V

In the accompanying drawings, A'marks a frame or support of suitableconstruction, upon which is supported and fastened two or more sidebearing supporting-pieces, a a, ar-

ranged transversely with the length of said frame or support, leaving aportion of said frame extending beyond one side thereof.

B B B refer to three pairs or series of feedrolls, with their shaftshung in the side pieces, a a, the rolls of each pairbeing disposed oneabove the other, and suitably spaced apart to enable the feeding betweenthem of veneers or boards of great thinness.

C is a bar or roll fastened to projecting pieces, either of the sidepieces, a, or of supporting-pieces for said side pieces, and arranged atthe front end of the machine, opposite therolls B, disposed thereat withits upper surface occupying a plane above the point of entrance betweenthese rolls. The object of this bar or roll is to enable the passing ofthe veneer or board to the rolls in an upwardly bent or curved position,as it is apparent that by inserting the end of the veneer or boardbetween the rolls the veneer or board will rest upon said bar or roll,and consequently from its elevated position cause the veneer or board toassume such position. It is found that by thus passing or feeding theveneer or board to the rolls it will be prevented from breaking orsplitting, as the crookedness therein resulting from drying will betaken out to a greater or less extent, and the veneer or board beprevented from buckling or folding together in creases, as it does inpassing or being fed as heretofore in a straight line to the rolls ormachine. This difficulty, which is entirely overcome by my machine, hasbeen a source or cause of great waste in smoothing, pasting, gluing, orotherwise treating veneers or thin boards. I therefore effect a greatsaving of material, and consequently am enabled to manufacture from thismaterial, which is very extensively used, cheaper and to a greateradvantage than by the methods heretofore employed.

'D is a sand-paper covered or smoothing cylinder or roll, with its shaftcl hung or supported upon a cross-pieceand the end piece of the frame A.Upon this shaft is the driving-pulley c of the machine, through whichand a belt connecting with a suitable motor motion is imparted to thecylinder or roll D. This cylinder or roll is arranged between the twoseries of rolls B B to act upon the ve
